Well my cooling fans are always staying on after i shut my car off and are killing my battery to the point that my car doesn't start. Some one told me that its most likely my cooling fan relay(the 4 by the passger side post) But how do i tell which one it bad. I was going to buy all four but there price is high, 3 are almost 50 dollors each and one is 160 dollars at the dealer.
Thank Mark T

 

I think Dale Clark told me a couple months ago some dealership was selling them new for $5 for all 4!

 

Just came home from the Rotary revolution. Met Ray Crowe from Malloy Mazda. He is as cool in person as he is with pricing and delivery of OEM parts

 

As I remember there are at least 4 relays involved with the operation of the cooling fans. I believe its likely a set of welded contact points in one of the relays, so be sure to do some circuit isolation or you could just swap/disconnect one at a time. I also might my self make sure the circuit amperage draw was normal. Just to make sure the new one wont just melt. John

 

Mazdaformance was the one selling new sets of stock relays cheap. Unfortunately they're both a) out of stock and b) out of business, according to their site.

I have NO idea what they run new - could be high, could be reasonable. Call Ray at Malloy up and get a price on them then go from there. Good used ones aren't too hard to find, but it's hard to beat a brand-new part.

so is there a way to check which one is bad?
Thanks
